Generating a fading process for the simulation of land-mobile radio communications

An appropriate design method for the correlation shaping filter used in the simulation of the narrowband land-mobile radio channel is shown to be that of a windowed-Bessel function. Thecoefficients are configured in a multirate filter, combining both the functions of noise shaping and image rejection, to allow the generation of a fading process with precise correlation properties with only moderate size convolutions at each iteration.
